Pruritus is highly prevalent in the dialysis population. Its etiology however remains often unclear with uremic pruritus primarily suspected unless compelling evidence of another cause. Although bullous pemphigoid (BP) is considered idiopathic, there are growing data in the literature on BP provoked by different factors, such as medications or surgical procedures. These secondary dermatoses are described as rather mild conditions and more frequent in the elderly Caucasian. We herein describe a newly dialyzed African man of 76 years old, treated by a sulfonylurea such as an antidiabetic drug, who developed a severe BP after jugular catheter placement.

The abundance of publications of COVID‐19‐induced chilblains has resulted in a confusing situation.

Immunotherapy has become the standard of care for various cancer types. The widespread use of immune checkpoints inhibitors confronts us with a whole range of novel immune-related adverse events. Skin toxicity is one of the most frequent adverse events. In this article, we report a case of anti-PD-1 induced late bullous pemphigoid (BP) with mucosal erosions and associated with a troublesome neurological disorder of undetermined origin in a patient with metastatic melanoma. Skin biopsy was essential to make the diagnosis and rapid initiation of systemic prednisolone played a role in favorable clinical outcome of BP. We will discuss the difficulty of early diagnosis of BP, its unusual association with neurological disorders, and the specific management of this particular dermatological entity.
